Su'aalo Tusaale ah oo Ka Hadlaya Afarta Xogta Kooxaysan
Pendahuluan
Rubucyada tirakoobku waa cabbir u janjeera dhexe oo xogta u qaybiya afar qaybood oo siman. Rubucyadu waxay ka kooban yihiin rubucyada koowaad (Q1), rubucyada labaad (Q2), iyo rubucyada saddexaad (Q3). Xaalado badan, xogta la falanqeynayo waa la kooxeyn karaa. Maqaalkani wuxuu ka hadli doonaa tusaalooyin iyo dood ku saabsan rubucyada xogta kooxaysan.
Fahmidda Saddexleyda Xogta Kooxda
Afar meelood meel waa qiimayaal u qaybiya xogta habaysan afar qaybood oo siman. Afar meelood meel ee ugu horreeya (Q1) waxaa loo yaqaan boqolkiiba 25aad, rubuc labaad (Q2) waxaa sidoo kale loo yaqaan boqolkiiba dhexe ama boqolkiiba 50aad, rubuc saddexaadna (Q3) waxaa loo yaqaan boqolkiiba 75aad.
Xogta kooxaysan, xisaabinta rubucyadu waa wax ka dhib badan xogta keli ah. Xogta kooxaysan badanaa waxaa lagu soo bandhigaa jadwalka qaybinta soo noqnoqoshada, sidaa darteed waa inaan isticmaalnaa qaacido gaar ah si aan u helno rubucyadu.
Qaacidada Afar-jibbaaran ee Xogta Kooxeysan
Si loo helo rubucyada xogta kooxaysan, waxaan isticmaalnaa qaacidada soo socota:
– Rubuc-kii ugu horreeyay (Q1):
\[
Q1 = L_{Q1} + \left( \frac{\frac{N}{4} – F_{Q1}}{f_{Q1}} \right) \times c
\]
- Rubuca labaad (Q2):
\[
Q2 = L_{Q2} + \left( \frac{\frac{N}{2} – F_{Q2}}{f_{Q2}} \right) \times c
\]
– Rubuc saddexaad (Q3):
\[
Q3 = L_{Q3} + \left( \frac{\frac{3N}{4} – F_{Q3}}{f_{Q3}} \right) \times c
\]
Halkee:
– \( L_{Q1}, L_{Q2}, L_{Q3} \) = xadka hoose ee fasallada Q1, Q2, Q3
– \( N \) = tirada xogta
– \( F_{Q1}, F_{Q2}, F_{Q3} \) = soo noqnoqoshada wadajirka ah ka hor fasalka Q1, Q2, Q3
– \( f_{Q1}, f_{Q2}, f_{Q3} \) = soo noqnoqoshada fasalka Q1, Q2, Q3
– \( c \) = dhererka fasalka
Tusaalaha dhibaatooyinka
Kuwa soo socdaa waa tusaale dhibaato xog kooxeed oo loo isticmaali doono in lagu xisaabiyo rubucyada:
| Qiimaha | Soo noqnoqoshada |
|————|———–|
| 10 – 19 | 5 |
| 20 – 29 | 8 |
| 30 – 39 | 12 |
| 40 – 49 | 15 |
| 50 – 59 | 6 |
| 60 – 69 | 4 |
Tallaabada 1: Go'aami Soo Noqnoqoshada Wadajirka ah
Marka hore, waxaan u baahanahay inaan go'aamino soo noqnoqoshada isugeynta ee fasal kasta:
| Qiimaha | Soo noqnoqoshada | Soo noqnoqoshada Wadarta |
|————|—————–|————————|
| 10 – 19 | 5 | 5 |
| 20 – 29 | 8 | 13 |
| 30 – 39 | 12 | 25 |
| 40 – 49 | 15 | 40 |
| 50 – 59 | 6 | 46 |
| 60 – 69 | 4 | 50 |
Tirada xogta (N) = 50
Tallaabada 2: Go'aaminta Rubuc-Qaad ee Koowaad (Q1)
- \ ( \ frac {N}{4} = \ frac {50}{4} = 12.5 \)
Waxaan raadineynaa fasalka uu marka hore ka sarreeyo 12.5, oo ah fasalka 20 - 29.
– L (xadka hoose ee fasalka Q1) = 20
– F (soo noqnoqoshada wadajirka ah ka hor fasalka Q1) = 5
– f (soo noqnoqoshada fasalka Q1) = 8
– c (dhererka fasalka) = 10
Isticmaalka qaacidada Q1:
\[
Q1 = 20 + \left( \frac{12.5 – 5}{8} \right) \times 10 = 20 + \left( \frac{7.5}{8} \right) \times 10 = 20 + 9.375 = 29.375
\]
Tallaabada 3: Go'aaminta Rubuc-labaad (Q2)
- \ ( \ frac {N}{2} = \ frac {50}{2} = 25 \)
Waxaan raadineynaa fasalka uu marka hore ka sarreeyo 25, oo ah fasalka 30 - 39.
– L = 30
– F = 13
– f = 12
– c = 10
Isticmaalka qaacidada Q2:
\[
Q2 = 30 + \left( \frac{25 – 13}{12} \right) \times 10 = 30 + \left( \frac{12}{12} \right) \times 10 = 30 + 10 = 40
\]
Tallaabada 4: Go'aaminta Rubuc Saddexaad (S3)
– \( \frac{3N}{4} = \frac{3 \times 50}{4} = 37.5 \)
Waxaan raadineynaa fasalka uu marka hore ka sarreeyo 37.5, oo ah fasalka 40 - 49.
– L = 40
– F = 25
– f = 15
– c = 10
Isticmaalka qaacidada Q3:
\[
Q3 = 40 + \left( \frac{37.5 – 25}{15} \right) \times 10 = 40 + \left( \frac{12.5}{15} \right) \times 10 = 40 + 8.333 \qiyaastii 48.333
\]
Gabagabo
Xisaabinta kor ku xusan, waxaan ka helnaa qiimayaasha rubuc ee xogta kooxda sida soo socota:
– Rubucda koowaad (Q1) = 29.375
– Rubuca labaad (Q2) = 40
– Rubuc saddexaad (Q3) = 48.333
Qiimayaashani waxay noo oggolaanayaan inaan fahanno sida xogta loogu qaybiyo kooxda dhexdeeda. Tusaale ahaan, 25% xogtu waxay ka hoosaysaa 29.375 (Q1), 50% xogtu waxay ka hoosaysaa 40 (dhexdhexaadka ama Q2), 75% xogtuna waxay ka hoosaysaa 48.333 (Q3).
Xisaabinta afargeeslaha ah waxay faa'iido u leedahay xaalado kala duwan si loo helo faham qoto dheer oo ku saabsan qaybinta xogta. Fahmidda habkan waxay noo ogolaanaysaa inaan si sax ah oo wax ku ool ah u falanqayno xogta kooxaysan.
